Application filed April 18, are. seen no. 184,626.

This invention relates to a new and improved fence construction, andmore particuiarly to such a construction adapted for use as a snowfence.

In certain sections of the country it is necessary to provide snowfences along highways and railroads to prevent drifting of snow on tothe highways and railroads. The fences cause driftin adjacent to themand must be in spaced away rem the railroad or highway so that the driftwill not be formed thereon.

For this reason in many localities it is neces sary to place the snowfences in cultivated fields. Since the fence would prevent the use 15 ofportions of the fields it is customary to remove the fences during thesummer. Also during periods of extended drifting it may be desirable tolift the fence and move it back further from the road or highway beingproeo tested. These fences as now commonly constructed, are formed ofwood which is subject to heavy loss from breakage and also from fire.The wood fence is usually made in panels which are removed and stackedduring the summer, and this moving and handling causes considerableloss.

It is an object of the present invention to provide a fence adapted forsnow fence uses, which is formed entirely of metal and which a may bereadily removed and replaced.

It is a further object to provide a fence of this character which may berolled for storage and which will then occupy but small space.

Other and further objects will appear as the description proceeds.

I have illustrated in the accompanying drawings certain preferredembodiments of my lnvention.

In the drawings- Figure 1 is a face view of a section of one form offence;

Figure 2 is a section taken on line 2-2 of Figure 1;

Figure 3 is a face view of a modified form of fence;

. i, r Figure 8 18 a section taken on hne 8 8 of Figure ,7.

The form of construction shown in Figures 1 and 2 comprises a pluralityof post sections 11 connected by a plurality of transverse wiresintermediate Linetal members or pickets 13 are securedtothe wires 12 bycl ps 14:; Clips 14L are also used for securing the wires to the posts11.

Tllie posts 11 are shown in "detail in cross sectijoii in Figure l.Theyhave the face portion 15 provided with the serrated upturnecl edges16. The'post is T-shaped in cross section having the rearwai'dlyextending leg- 17,

the outer ed ge of which is formed with the bulb 18. his post has quiteconsiderable resistance of bending in any direction.

One form of intermediate member or picket is shown in Figures 5 and 6;It consists of a flat face portion having upturned serrated edges 19;

tion generally similar to the face the posts 11.

It is shown as" a light rolled secportion of but somewhat wider andlighter.

Another form of intermediate picket is shown in ures 7 and 8. Thispicket 20 is corrugated in form as best shown in Figure 8: It isprovided with an intermediate depressed portion portions 22 portions 23.

21, with outwardly rounded and with intu'rned serrated edge This form ofpicket may be rolled and cut from sheet metal and thus is lighter andcheaper to produce than the rolled section of Figures 5 and 6. Due toits corrugated form, however, 1t possesses considerable r1gidity. Tinsform of plcket is shown held gether clips.

for shipment or storage.

The form of construction shown in Figure of 3 is provided with posts 11which extend for some distance beyond the lower edge ofthe intermediatepickets. These lower portions 26 of the osts are provided with spades 27to aid in hol ing the post in the ground. It will be understood thatthis form of fence is not provided with the supporting. legs of Figure'2 but is held in the ground and supported by the post extensions andspades or anchors. It is possible, however, to remove thisfenceforstorage or shipmentby an upward pull upon the fence post which willdraw the post and spade up out of the ground.

While I have shown certain preferred forms ofposts and pickets, it willbe understoodthat'these forms may be further modified and I contemplatesuch changes and modifications as come within the spirit and scope oftheappended claims.

I claim: i

V 1. Fence construction, comprising metal posts, wires connecting saidposts and metal pickets, the metal .picketsbeing connected to thewiresintermediate the posts, legs hingedly connected to theposts, the postsand pickets being so connected to the wire as to permit the entirestructure to be rolled for shipment.

2. Fence construction, comprising'a plurality of parallel wires, metalmembers extending transversely of the wires andsecured to the wires'inspaced relation, certain of the metal members eing longer thanthe othersand'adapted to serve as posts when the fence is erected and legshingedlyconnected to the longer metal members.

3. Snow screen construction comprising a plurality of parallel wires,members extending transversely of the wires and secured to the wires inspaced relation, certain of said members having ends extending beyondthe adjacent members, and legs pivotally secured to said extendingmembers and adapted to be against the members when the structure isfolded against said members when the structure lsrolled for shlpment. IV I 4. Snow screen construction comprising a plurality of parallelwires,-metal members extending transversely of the wires and 'se-, curedto the wires inspaced relation, certain of the membershaving legspivotallysecured thereto, said legsbeing adapted to be folded rolled forshipment. r

"5. Snow screen construction comprising a plurality of parallel wires,metal members extending transversely of the wires and 'se- [cured tothe'wires in spacedv relation, certain I of the members havingrearwardly extending flanges whereby their'resistance to bendingiis'increased,-l"and legs pivotally secured to fla g aid legs, beingadapted, to be Signed at Duluth, Minnesota, this 11th day April, 1927.
